Not too difficult if you don't play the events.
Daily stamina: 140 from PWN, 100 from PWN shop, 50 from aether shop = 290 stamina.
Add 40/week from guild rewards.
Takes about 34 days to max stamina from zero.

Hey folks, sorry for the delay! After some consideration, we have decided that we will not be adding the quests again, but will be sending the rune that would be paid out by the last step of those quests to any players who made any progress on the quest and did not claim the last step of the quest. I do not have an exact date for when they will be sent out, but rest assured that I'm pestering the people in charge of such things on your behalf.

What about those of us who spent gems and/or stamina and/or gold to finish those quests??? No compensation for us? These players are getting the rewards (compensation) without having to do the effort. Compensation should be made to all.
